Technical specifications


Surplus room in each frame is filled out with solid E-Blocks. Called spares, they bear the designation A/0. The copper sheet forms contact between surrounding blocks and the frame. E-Blocks are referred to by their width, followed by the designation /0 (indicating solid). Thus a E-Block with a width and height of 15 mm is referred to as 15/0. The length of E-Blocks is always 60 mm.

Special and larger modules can be made to order.
